A bolted connector includes a bulk head for connection to a column and a plate extending from the bulk head for connection to a beam. The bolted connector is preferably die cast for ease of manufacturing to avoid welded connections which may provide structural weaknesses. The bulk head has a compact tapered shape which provides a reduced surface area end surface coming into contact with the column. This reduced contact area of the end surface provides an advantageous configuration which avoids the prying action of the prior art T-shaped brackets. The plate which extends from the bulk head includes a plurality of bores for attaching the plate to the flange of a beam. The plate has a first thickness at a portion of the plate which is adjacent the bulk head and a second smaller thickness at a portion of the plate furthest from the bulk head. The variation in thickness of the plate allows the strength of the connector to be tuned to the amount of stress which the plate will be subjected to at any particular location.
